As an alternative to the Vollee mobile phone Second Life client I wrote about a couple of weeks ago, there’s this Samsung mobile phone due out later this year in the US which also claims to run SL.  The Blackberry-style phone and keyboard do seem to lend themselves better to the SL experience than the regular type of phone featured in the Vollee demo, though Vollee does seem to offer more flexibility in general.   It’ll be interesting to see which, if either, of these take off and how well they actually work.  I don’t know, you wait forever for a mobile solution then two come along at once
