Originally i had no joy whatsoever getting my TR1MP to use my 8910i as a bluetooth modem, as bluespace ne was essentially useless, however having just recently updated bluespace ne from sony i decided to give it another go, and to my suprise it all works flawlessly, and i can connect via Orange GPRS with consumate ease.
Now i just have to hope that when i change over to a TR2MP and a Nokia 6230 soon it will be just as easy.
Hope this helps you make you decision, i actually got my 8910i to replace my SE P800 for £270, but as it cost £500 at the time i couldn’t pass up on a phone that looks and feels this nice (even if it does lack most of the features of more modern phones).
