Skype chat you can do with IMO premium which is about $40 and IMO which is free, they both multi chat apps supporting all the tops, skype, msn, gtalk, yahoo, facebook, etc. Personally i use IMO on both my Droid and Berry even though i paid for IM+ (their is a free 1 but skype only works in 30min sessions). I use IMO as imo.im is much nicer than plus.im, thier web browser based "desktop" versions of their chat apps.
There are a lot of issues with plus.im that imo does not have but they do both sync your histories between the desktop and mobile versions. IMO has the added advantage of account linking so if you setup your linked accounts on thier site then you only need to use any 1 of those accounts to log into on the mobile and it will auto connect on the rest where as with IM+ you need to enter the details for each account you want to use whihc can be a schlep if you change phones or your phone breaks and gets reset. IMO also supports a wider selection of chat protocols including the newly added steam(as in the game thing).
If you just looking for text chat then those 2 are your best bets, if you don't want to drop $40 then IMO is your obvious choice and IMHO the best by far from the 2.
