Alright I have an iphone 3g, I have jailbroken this iphone a while back when the 2.2 update came out, well recently it started giving me problem "it wouldn't let me answer incoming calls", so I decided to upgrade to the 2.2.1 and jail break it, so I followed all the steps correctly but now when I open quickpwn and plug in my iphone it wont even recognize the device, also I am running a mac with OS X 10.5.7, I know I should wait for the official 3.0 update but I dont know if this problem I am encountering with happen with the next update, someone please help

thank you for your time
