Don't give up your vision plan. The megabyte plan only covers usage of the phone as a modem. If you surf the web on the phone without the vision service, you'll be charged $.01 per KB. Also, the greatest deposit we charge at Sprint is $250 per line. It is returned in your 11 month of service in good standing as a credit towards your bill.
Yeah you were right on the vision plan: If I was doing it again I would still get the 6600 with just the data plan but I would also get the sanyo 200 for voice. Oh and no deposit required can have up to 6 lines $900 credit limit. luckly I got the phone before I filed bankruptcy.
