It sounds like to me, however, you will want a BES setup, in order to have what you need, with the old mail and calendar items.
Small point, but I bought a brand new UK 8310 from t-mobile, and it only has 56MB memory. Less than the 8800, with 64. Maybe that is why it is cheaper? Also, the "older" 8700 devices had 72MB. Not really sire why they vary so much...
