Ok here is the situation, I have an iPhone 4 that is supposed to be unlocked. It was on 4.02 and baseband 1.59.00 I used tiny umbrella to upgrade to 4.1 without upgrading the baseband and it worked. I got a Tmobile sim card, and cut it (not that great) but when I put it in to the phone it says T-Mobile, I can make calls, however the guy at the T-mobile store said that because the number is being ported it could take up to 24 or 48 hours for everything to work right. So like I said i can make calls, but when I get a call it will not ring it will say my phone is off, also I cannot write/recieve text messages, even though I got an unlimited text plan. Now, my issue is with Wi-Fi Ever since I put the Sim card in, under general Wi-Fi it shows the wifi unit we are using and says its connected however in the upper left hand corner their is no wifi signal, and I cannot connect to anything that uses Data. I tried turning the phone on/off, resetting network settings, and still the Wifi will not connect. Can anyone help fix this.
