OMG!!! my phone is working again!
i put the sim and voila! i have no idea how this worked but it did, thanks very much everybody for your help, especially hardost (i think your way is the main cause that it worked again).
sorry for the triple post
so did it just work or did you have to do what the other people suggested? Just im looking on ebay and can get a n80 for real cheap but its stuck on offline mode and i wana know if i can get it to online, wether its worth the money
