Hey guys, i don't know if anyone has ever had this problem, but ive been searching for an answer and I can't really find one...

I have this problem where whenever I log into appstore or wifi and try to connect... the password box only lets me do only ONE entry (Numbers or letters). I don't know how to resolve this problem and was hoping someone here knows what the heck is happenning to my iphone 3g. Btw it's jailbroken with 2.2. Let me know! Thanks!
