    Default Custom 3G Device for Iphone

    Now that people are starting to get their hands dirty and making external microphones for ipod touches combined with VOIP software packages and GPS devices all hooking up to the custom USB port at the bottom of the iphone.

    How difficult do you think it will be to make custom 3G devices that hook up to your iphone port? Or hooked up to a wireless network (lets say in a backpack or car) and connecting to this custom wifi hooked up to 3g combo. Yea that last one was definitely fantasy but I think the first option may be possible. What are your opinions?

    Almost certainly won't be a reality, Apple will almost definitely bring out a 3G phone and thus negating all market for this device. Too much R&D funding needed as well as the fact it would eat up way too much juice to be worthwhile using. There just isn't a market.

    P.S. its not a "custom usb port" the dock connector is a proprietary serial port that can handle USB as one of its functions.

    actually they wont be bringing a 3g phone at least till june of 2008 or possibly later, so it will be a good addon to have between now and the time it comes out next year. Yea, well people can just use it while its plugged up to a car or wall charger. Its external, it doesn't have to be plugged in all the time, it can just be disconnected. Or you can just use it for a few minutes while you are on the internet and just disconnect it when you are done. So, battery shouldn't be an issue. I'm sure there is a market for it. Many people want 3G for their iphone. ATTs and sprints 3g services are available every place I go in California.

    But, one possible good point you may have had is that R&D funding would cost a lot. However, I need you to elaborate with an actual argument in order to obtain a better understanding of how you arrived at your conclusion

    I'm just saying that big corporations always target the biggest market, or if they do target a niche market they tend to make what they produce quite expensive to cover their own expenses. It's all about supply and demand. Also people don't usually want loads of crap sticking out their phone. I know I wouldn't use an iPhone with a box sticking out the bottom just to make a call. Also look at the 3G devides for laptops, you buy those separately and they're quite expensive.

    Also I forgot to mention the device would probably require the use of an additional SIM card as I doubt the iPhone official ones are 3G compatible.

    I see. Good points. I didn't know the people that are making the gps device were a corporation. I thought they were a garage team turned entrepreneur. But, I'm sure you are right. They are probably a large company. Are the external 3G devices that large? I know the 45nm 3G chips are much smaller now, but I guess they haven't been mass marketed yet. I'm going to do a little more research into this. Maybe this could be my project for my winter break. I've never worked with Apple or mobile products before, so attempting to integrate new hardware with it would be fun. Maybe I can get a few of my friends from Raytheon in on this if my research goes well

    Thanks for the information

    Ok, so it could be done by a small team but 3G is a little different as there aren't so many off-the-shelf components they can tap into like they can with GPS. Also for the size I should expect it to be about the same size as the GPS if one was made, Ok, so it isn't THAT big but it's still quite big compared to the iPhones form factor.

    How about a satellite wifi broadband modem.

    I can not find references to them on the internet much.

    However I saw one on pimp my ride once. It would appear as a wifi access point to the phone.

    Not portable but if I had my car parked up outside the auction house I frequent then it would certainty help me search eBay from the auction house at broadband speeds.

    Anyone know where to get one of these gadgets from.

    You could have a 3g phone by buying a 3g modem for a laptop, and either using ad-hoc networking or by buying a wireless router to broadcast your 3g internet to the phone, not really sure where you'd get a backpack that does all that though..

    I know someone that used to use Satellite broadband and (in the UK at least) it costs an absolute fortune a month, >50 usually, also there is a LOT of lag as you gotta get the singal from the satellite, thats why many used to use ISDN for the upstream connection to reduce lag somewhat. The speeds are good but v high lag.

    Satellite internet has gone the way of the dodo. I am almost positive that EDGE is actually faster. They do have portable WIFI routers with 3G modems, that's probably what you would be looking for.

    As far as a homebrew extension, I would almost guarantee you that it wouldn't happen. As neonkoala mentioned, there aren't really any 3G chipsets available for DIY hacking simply due to the intense amount of governmental regulation behind all things wireless. Such a device would need to be approved by the FCC (here in America) before it was sold, a crapload of red tape to cut through I'm sure. After all that, you would still not be seeing a huge jump in data rate because 3G shares the same exact latency problem that EDGE suffers from. What 3G is useful for is downloading medium-large files. As far as web browsing, the difference is not dramatic. And to really put a spike in that coffin, your battery life would decrease to like 30 minutes. The fact that this thing would be an external module would increase the amount of overhead power requirement (due to the interfacing, etc.). And you would also need a separate contract just to run this thing as you would need another sim. Long story short, it is never, ever, ever going to happen, never. Sorry to burst your bubble, but those are the facts.

    Oh, did you hear? The iPhone's modem is software upgradeable to 3G.
