I have an unlocked 3g iphone. Heres the problem,I unlocked my iphone with blacksnow and everything and it seems like everything is all good. My tmobile sign is showing and I have a couple bars. The problem is sometimes when I call someone they can't hear me or vice versa and then sometimes the searching for networks sign starts to come up. I tried reinstalling and rebooting everything and it still happens. I took my tmobile sim card out and put it in another phone and it works perfect. Could this be a hardware problem or software problem. Any help is appreciated thanks

These type of voice problems are 99% of the times related to T-mobile itself. There have been thousands of reported outages this week. I used to get those problems a lot when I lived in VA, not that much in FL. Give it a couple of days. Maybe your cell phone tower is over the quota.

Sounds like hardware. Did you drop the phone at any time?
