i am unhappy with nextels text messaging also. it is very slow.
on my 7100i i dont see an option anywhere to send SMS. so i am going to take off my unlimited text messaging, and add a data plan, so i can use the internet and all. my AIM will still work right? (i am using ramble, which works pretty good!)
i love the walkie talkie feature, but the texting is horriable
may have to go back to cingular... idk i dont want to though.
