randomly can't get incoming call, unlock related?
Hi I have a 16G 3G jailbroken at 3.01, unlocked w/ ultrasnow.. my network carrier is tmobile.. its been a problem for awhile (prolly why i dont get call as often lol). At times I cant get incoming calls, no rings, no vibrate, nothing appears on my screen or gets registered as missed on or incoming call even with full bar of network signals.. The next thing i find out is a voicemail otherwise i wouldnt know if someone called and didnt leave a message. The caller hears my phone rings but on my phone it shows no one calling, its starts to get annoying. Sometimes it works perfectly fine and then randomly does it again. I can make outgoing calls and text fine but i did notice some delays in text messages too.
Anyone knows if this is jailbreak unlock related, or any fix to the problem?
