hi, i JB'en my iphone like million times before but this time was different cos i had to activate my 10.5.6 system, and also i just switched to mac so did a restore to have it mac formatted and so on, to be able to detect in in DFU mode. never had any problems. installed winterboard and few apps and now every time i try to go to use my iphones phone option it goes back to SB and does not allow me to dial a number , check voice mails or go into contacts. it freezes for 4 sec and go back to SB. i can call by going to contacts but cannot dial a number.
what you think ? what might be the cause?
