Hi ppl,
I had updated my phone with 3.1 just two days after the launch…since that time there was crack available for 3.1, downgraded the software to 3.0..but since the modem firmWare is changed to 05.11..the phone was unable to read the sim card… Now finally when blacksn0w is released with a crack…I’m unable to unlock my phoned with the same since it depends on the software to be 3.1

can some1 suggest me some alternative…please

I haven’t kept track of jailbreaks and updates since i got my own done.
But then a friend of mine purchased a new iPhone 3GS, it worked and i installed Cydia and Rock, but after a simple “reboot” of the device, it goes to recovery mode.

What’s the solution? Any patch or new jailbreak update?
Thanks.

Hey Guys… so i have a very special problem here

I have an iPhone 3G 3.1.2. BB 05.11.07 from Germany which I want to use in Canada for the next 5 months. I went to Rogers yesterday, made a contract and everythings fine so far, i can call and text. but each time i start safari i’ll get an errormessage telling me that i did not subscribe to a cellular data plan, which i did! 500 mb/month, i got that confirmed from rogers. they also told me it was definitely the right plan for an iphone.

i jailbroke with cydia and installed blacksn0w, which gave me access to rogers, but even using blackra1n would not give me the app an the iPhone to use sn0w.

any considerations?
