Ok Renkin. Firstly the 7100g is an excellent device and does quite a lot for the price. This will make a great gift for any business person.
As it relates to which network is favorable, I implore that you consider a Blackberry service rather than simply a gprs service, otherwise you will be wasting more of the device'f features.
A feature that I like myself is the live sync with your outlook contacts and inbox. That is, if you add a contact in your phone, as long as your computer is on the net and your outlook is open, it will automatically add it to you outlook contacts. (This being your choice that is).
Another feature is the "push email" service. Where POP3 mails are automatically sent to your phone (if setup) as soon as the mail is sent.
Free Thinkers are those who are willing to use their minds without fearing to understand things that clash with their own customs, beliefs for privileges. This state of mind is not common, but it is essential for right thinking; where it is absent, discussion is apt to become worse than useless.
