old bberry, jabber/xmpp, plus sip?


New member

I found back a old blackberry curve 9320, running bbos 7. It's old, older than the one with andro4 compatible layer.
I was wonderig about if it's possible to add application software on it, such as a sip client, a jabber/xmpp client?
Id really like to give it to my niece whom is a teenager, and needs only phone/SIP(voip) and jabber utilities...

is it possible to do so?
I thank you vm
