Hey guys,

I just bought an iphone 3gs used. i use to own a 3g that i gave away but i realized i missed using an iphone. the 3gs i bought came with os 4.0. but i've started to encounter some issues.

1) the texting keyboard lags sometimes when i type fast/doesn't catch certain letters when i type fast

2) bluetooth to my JVC car stereo is chopppy and cuts in and out whenever it feels like it

I was just wondering if anyone has encountered the same problems and perhaps have any remedies. or would it be advisabele to just update my firmware to 4.1. its currently jailbroken.

thanks in advance
