Trillian

Runs seamlessly on W7, BBOS 6&7, Android HC & ICS and that other POS from Cupertino. 

If yahoo would make their client compatible with the rest of the world, everything would fall into place.

In case it works, then it works almost fine /freezes/. The main problem is to login, it takes more then 75 minutes or sometimes it is impossible at all.

I bought this app thinking it would serve as an IRC client like all other Trillian versions do. As an IM app it does nothing special. If there was a refund option I'd use it.

This app drains batteries big time and it is very hard to read because it is so dark. It's a waste of money.

Works like a charm, good message delivery. Easy to use interface. Sadly it's a bit too simple, they could add some more features and options.
Also, the icon is disgusting/ugly. Only because of this icon I'm giving 4*

This should come preinstalled on every BlackBerry device. Can't live without.

Work great for me, & my fb chat does work, but I've been using trillian on my computer for years & have an account with them & my fb already linked, maybe you should try on the computer if u can't link ur fb to trillian.

Endlich auch für den Bold 9900. Läuft fehlerfrei, beinhaltet unter anderem MSN, ICQ und Facebook Chat. Trillian ist und bleibt einer der besten MultiMessenger und läuft stabiler als Nimbuzz!

Had this for more than a year, use it for 5 instant message accounts. To those who say it's slow, check your phone's app memory; maybe you need to reboot your phone to free some up (alt+right caps+del). I have it running constantly on my memory-poor 9000 and love it

Getting it from App World is a horrific pain in the arse. 
I have never used such a buggy unpolished system from a major company (RIM) as this. I have gotten to the point where I dread updating apps because the may or may not show up on the device after a reboot. 
Now I get an error message (ID 30220) when I try to reinstall Trillian from BAW. Blackberry I have been with you since the original Pearl but you are making it very difficult to support you with your constant release delays, ho hum devices, outages, crappy apps, and buggy software. 
Step up or step aside. I keep giving you chances to disappoint me and you never fail. 

For some reason this wont reinstall on my BB. Great programme but coming up with a payment error.  Support is pretty much non existent

Facebook won't work at all I tried to uninstall the app it won't let me download it back again :(
