I've never posted eBuddy 1.5 because it doesn't install on my i776.  Plus it's supposed to be a very minor update to fix a connection issue on some non-Boost phones. On the other hand eBuddy 1.4 works, although it keeps telling you there is an update available.

Boost apps reader Darren found a version of eBuddy 1.5 that does work on his i9. I tried it on my i776 and it  fails with a "Class Loading Error on "bz.class" just like the other one I tried.  I'm posting it anyway for the benefit of i9 users.  It may work on other models with likely candidate being the i856 because it is the latest models.

If you try this on a phone other than the i9, please post a comment saying if it works or not and I'll update this post.  If you try it and it doesn't work, you can always go back to eBuddy 1.4.

eBuddy is another free instant messaging client similar to Nimbuzz.  I like Nimbuzz but some users prefer eBuddy and I've gotten requests to add it to BoostApps so here it is.

eBuddy supports Yahoo, MSN, GTalk, AIM, ICQ, MySpace and Facebook. The "Lite" version of Nimbuzz that works on iDEN phones supports Yahoo, MSN, GTalk, AIM, ICQ, Skype, GaduGadu, Hyves and StudiVZ .

One thing that that eBuddy and Nimbuzz have in common is that the keys are mapped incorrectly on iDen phones, use these workarounds.
