Dear David,<br /><br /> My immediate answer would be 8525! <br /><br />Samsung' Blackjack is a smartphone and 8525 is a HTC Hermes with Pocket PC OS, obviously superior. Smartphones lack touchscreen and there are not many softwares for it like Pocket PC. Blackjack is under complaint for bad battery life too. Poor for Samsung.<br /><br />Price wise, Blackjack with 2yr subscription in Cingular comes for $199 USD and 8525 could run around $499 USD but its worth it!<br /><br />You can ofcourse dial wirelessly with bluetooth headsets on all Pocket PC devices, provided you have saved the contact under Voice command.<br /><br />You can use a Pocket PC as wireless modem for your laptop but I'm not sure about smartphones on this. I'm also not sure about Cingular' data plan as I'm not in US

<br /><br />So finally, if i were to choose from the both, il definitely take 8525 though it runs for a little higher price.
