Hello,
I don't know if this will help but O2 in the uk have BB connect available for their XDAIIi which is a PDA, not entirely dissimilar to the HP hw6515...

You will need a valid IMEI and need to fill out certain details to get to the download page.

Please let me know if it works - one of my ex-BB users has just bought an hw6515 and is hoping to get BB connect working... he travels everywhere - if anyone can find the weaknesses in the product - it's him.

Regards
