Mobile Chat and ApolloIM are both 3rd party applications that are added using iBrickr or a similar program. They save you the time of finding the website and such. They are both pretty cool, but, as the consensus can tell you, Mobile Chat definitely has the better application at this time.
I had been a huge mobilechat user but I switched to apolloncause when I would be in a Conversation I would have to keep scrolling down the page to see new messages, anyone else get that ? Which one in evsryones experience stays connected better ?
