How to text with other phones non-blackberry
The 6510, 7510, and 7520 blackberrys are not capable of sending text messages (at least as of October, 2005 with handheld software os4.0), but it can receive them. When receiving a text, you will get no headers at all--just the message--so unless the sender puts their name in the main message, you won't know who it came from. This works fine for news alerts and so on, but not for staying in contact with your friends.
As far as sending messages to other phone users, there are two solutions:
1.Using carrier extensions. Using these email extensions, you can send a message to email@example.com, and they will receive the message just fine. The only problem with this, is that you have to know what carrier they are on to message them. The extensions for most North American Carriers are listed below.
Sprint-- @messaging.sprintpcs.com (not positive on this one)
U.S. Cellular-- @email.uscc.net
Bell Mobility-- @txt.bellmobility.com
2.The second option is great for when you don't know what carrier the other individual is using. You can send a message to firstname.lastname@example.org, and this will work equally well. This service will automatically determine the carrier and deliver the message to that cellular number. This service has been reliable for me, but I don't use it all that often. Others have said that it is not as reliable, YMMV. Also, teleflip adds a signature at the bottom of each message, just so you know--this will count in the character count of the message, and may cause the message to split into two when it is delivered to the phone, depending on the phone/carriers email/text capabilities--just an FYI.
