Did you guys even bother to read the pop up window? Chill out while they load up more servers.
Parlingo does not do the same thing at all... This keeps you active when you close the program and SMSs you when you get a message.
if you ask others to chill out, please do not give out FALSE info. mobilechat will only sms you for aim messages and not for yahoo, msn, or gmail messages. This makes it pretty much useless, because guess what, AIM already has a sms messaging system and has had it for a long time, long before mobilechat and the iphone came along (that i'm pretty sure mobilechat is pretty much leveraging as opposed to building something proprietary), where you can setup the desktop AIM client to SMS your mobile with any messages. For yahoo, msn, or gmail, mobilechat is simply waiting for the Apple push service in Setember so mobilechat didn't really do anything special.
