Any updates on this yet or do we have to upgrade to BaseBand 6.15.00? I have been patiently waiting and it does not appear that they have cracked the SIM issue for 5.15.02 and 5.15.04 - are we still the unlucky ones who are STUCK? Any suggestions on what we can do? Thanks guys.

Nothing new here to report yet. The only solution at present is to upgrade to 06.15.00....

Thanks - I guess, my patience is running out; will go with 06.15.00. Thanks again for confirming.

Trying to unlock my iPhone 4.. any help?

KnowledgeHouse:

1) Don't threadjack, your post has nothing to do with the original post. This is considered rude.
2) It's impossible for anyone to give you help if you provide absolutely no information in your post. If you want help, we'll need to know what version of iOS you are running on your phone and what baseband revision you have at bare minimum. It will also be helpful for us to know what carrier your phone is locked to and what carrier you intend to use the phone on, though we can likely assist without knowing that.

Not trying to be a jerk but please help us help you -- we can't do anything with 'Trying to do x/y/z, can you help'. Let us know what you've already tried, what the outcome of any previous attempts are (or just say you haven't tried yet, if you haven't), etc. What you did is like calling your doctor on the phone and saying 'I don't think I'm well' and expecting him to know what the problem is, based on that single sentence. Just doesn't work.
