Samsung BlackJack II SGH-i617

Can't set full songs as ring tones 300kb max

Can't modify txt msg ring tones (if you know how let me know, I’ve looked)

Internet seems to lag on mine, idk if it's with all of them

Internet button automatically goes to att's homepage; have yet to find a way to modify that

No thumbwheel

"The Wheel" is too sensitive that it causes me to select something I didn't mean to
Ex: I'm scrolling to select the sounds folder, as I move my finger to click on the center button I accidentally touch "The Wheel" and it scrolls down, at the same moment I click the select button, causing me to choose the Notes folder instead. This problem starts to become very noticeable once you start playing Bubble Breaker.

Can't modify "Contacts" on the home screen, on my BJ1 I was able to change the title from "Contacts" to "My People" or something else, seems kind of dumb that I can't do it on the BJ2
