When unlocking your phone from TMO, is the "restore as new" step required? I've read that it is needed and then I've read that some users didn't restore. I went to iphoneimei plugged in in my info and it shows my phone is unlocked. I've connected my phone to iTunes and saw no "congratulations" message like the email stated. I followed steps 1-3 as there is confusion on step 4. If I have to restore then I'll restore. thanks ====== T-Mobile Sim Unlock Request Sim Unlock Reference: ######### IMEI: ################# Unlock Code: Thank you for taking the time to contact T-Mobile.
