Well im currently one of those wqhos trying to use the jailbreak. Well lets just say... its HARD not easy to do. But when you get the hang of it you will succed. Currently i have mine "Jailbroken" but i forgot to select Cydia :'(! So ive been trying to get it to restore to vanilia 2.2.1 again (Finaly succeded doing that). Now i hope my next try on the jailbreak will work out well. Wish me luck lol.
