AIM over SMS and the regular AIM i dont think are real time like the regular computer ones..........i think that it updates the buddy list and new conversations at certain intervals........it also depends on your carriers network..........some might use realtime connnections........some might not and it also depends on whether or not your using an application....i use the web-based client and it was really slwo but the application wasnt much better
The various networks have different ways of using AIM or other instant messengers applications. When I was with Cingular most of thier phones have an IM client for AIM, MSN, Yahoo, etc that works very similar to the version on your PC. A little more awkward due to the small screen and keyboard but still it worked. With Nextel, they had an AIM client on thier phones. (been awile but I think I remeber and AIM client on my phone, or a way of getting one) With T-mo they have thier own OZ client which can connect to AIM, and the rest, but not as clean. Many of us with BB's on T-Mo will use third party apps instead like Yak-On, Ramble as they seem to function a little better thant the client that comes pre-installed
i found a free version of AIM Mobile somewhere but i cant remember where........it was supposed to be like 29.95 but i found it for free..........probably illegal but it was an old version and it was for my HP iPAQ but i think there was one fore some hones but it might be strictly for smartphones or something.........my iPAQ was just a standard PDA
