i have recently updated my iphone 3.0 framework through itunes and unlocked my phone through redsn0w. now every thing is working fine but i am not able to access internet through edge. as i have allready updated my career.plist to enable edgeediting, and my phone allows me to edit APN. but after this option my iphone does not allow me to use internet via edge.
please provide me the solution,

I was once iPhone user but am currently using N95-2 8gb, advice jailbreak and unlock again there might me a glitch while you were jailbreaking your iPhone it has happens alot some times pple experience not having network signal at all, do the process again goodluck.

if u using MTN, u wont have any problem, like me i upgraded to 3.0 and jailbroke and unlocked. and i use MTn 3G , tho its not free, still tryin to get around that. i also TETHER it wit my laptop and browse from it. it doesnt zap money like dat.
but when i put my zain sim it never works or browses. so try it wit mtn first b4 u go jailbreakin again
