Apps to track down a missing/lost iPhone

Was wondering if anyone would be willing to offer recommendations on App Store Apps, or Cydia (jailbroken) Apps, that could be used to help find an iPhone that you've misplaced or lost??

I've just now found my iPhone (about 5 minutes ago) that I've been looking for ever since last night, and I was on the verge of believing that the phone had absolutely fallen off the face of the earth, because I'd searched everywhere imaginable for it without a shred of success. (and yes, I of course tried calling the phone, but I was pretty sure it was on vibrate...and now that I've found it, I can confirm that it was!)

I'd read a review of a Cydia (commercial) app offered by iFoneTec called Cylay, which in all honesty, I found to be an absolute joke of an attempt to make what would otherwise be an indispensable application (it never once worked for me, wound up being un-installable, and inevitably wound up forcing me to restore my phone and start from scratch).

There must be at the very least several other apps (App Store & Cydia) that would have saved me a lot of hassle over the last 24 hours as I searched relentlessly for my iPhone without success...

Ideally, and app that could provide GPS mapping that can be somehow checked from an alternate location (or iPhone) would have done the trick...I've thought about Loopt as a possibility, and then using my Wife's iPhone as a means of finding my iPhone should it ever get lost again in the future (to at the very least let me know if it's in my apartment, or in my Car which is located in the parking garage around the corner, or at my Mom's place, of my wife's Mom's place, etc...)

Anyone else care to offer any thoughts or suggestions that might be worth trying?

Thanks!

No app store app is going to help you. For an official app to do anything, it needs to be open (no background processes), which obviously defeats the purpose.

I remember reading about this guy who came up with a solution. He wrote a script that constantly posted the iphones coordinates on twitter every 15mins or so.

Of course, the ability of the phone to locate itself varies widely on conditions. You could get coordinates that appear to move or are miles off just because, for example, the phone is under the seat in your car and its a cloudy day.

Constant GPS tracking would also drain your battery faster than holy hell.

This is kind of off topic, but I always wanted some kind of silent switch override code. Similar to how you might access your voicemail from a landline, you could enter a pin and the silenced phone rings. Crap, I should probably patent that idea before I say anything...:)

I think it's called iLocalis, or maybe just Localis. It's available through Cydia. I've used it a bit, and because I've got a 2G phone, the tracking is close but no cigar. The 3G version would probably be killer, though. Give it a shot. NOT an App Store app, obviously.

I tried iLocalis...IT WORKS PERFECTLY!! It does exactly what it says it'll do, and exactly what I needed it to do! Read more about it here...

Thanks so much for the recommendation. I wish I had this the other day when I misplaced my phone :)

I have seen lot of tracking software in the market with amazing features and economical price. Try to take the help of Google in this regards for most suitable results.
