Could anyone recommend the best IM app for iPad? In particular I'm looking for something very simple that allows iPad (or iPhone) users to send messages that look like SMS's with PUSH notifications. I used to use "Ping Lite" or "Ping Chat" and that was perfect, you just had to create a Ping user account, and off you went! But there is no full size iPad sized application for that.
Any suggestions would be much appreciated Note I'm not after something that necessarily does all the MSN/ICQ/Skype combined etc etc, just something simple that simulates 'SMS' sort of!
