I have Nokia 6230, and wish to install an IM application to use my MSN contacts on my phone using GPRS.

On Nokia's website, - subsection SHOP, there are 2 applications available for this purpose:
a. X-Messenger Lite ( Devlpd by XCome Technology)
b. Active Alerter ( Devlpd by Lucian Darie -- Java based )

If anyone has used any of the above on 6230, pls give me some comments / advise about the user-friedliness, and stability.
