i recently jailbroke my iphone 3gs on ipsw 5.0 using redsnow 0.9.9b4...it jailbroke no problem...i fixed the no service problem by downloading ultrasnow thru cydia....
but my problem now is that when i try and download a theme or somat cydia crashes and then it says no service again and i reboot phone through redsnow again and its back on...even if i turn phone off then back on it says no service
its literally doing my head in and im wondering if there is a solution for this please help
search Cydia for Corona and install it. then reboot to see IF it works properly. make sure you're near your computer just in case you might have to do a tethered boot
OR
you can download the latest redsn0w on your computer, run it but make sure to deselect the Cydia box when asked
---
due to my OCD i would just restore as new and re-JB. but hey, that's me..
iv downloaded that corona thru cydia and it worked but after 10mins jus picked up my phone and its sayin no service again so im gonna try 0.9.10b3 redsnow and rejailbreak it
i guess i will take part of blame due to me not reading the original post clearly. obviously when the OP mentioned ultras0w i should have caught onto that
now, i am not sure where that leaves him/her. can a 3GS with iOS 5.0.1 and updated baseband be unlocked? i have no idea. i guess go ahead and try the ultrasn0w [DL] in Cydia and see what happens
hopefully someone else that is more familiar with this situation will chime in
