a few things you didn't know your cell phone could do

1) Google
Did you know you can google without having wap 2.0 service or browser? Well, you can! Simply send a text message (SMS) to 46645. A bot will respond via text, and will give you listings. If you prefer a more human approach, there's a live service called Chacha, in which live people respond, giving more accurate results, but it takes longer, and is subject to human error.
2) E-mail.
You can also receive, and sometimes send E-mail. For example, to E-mail a phone simply type 2345678910@message.alltel.com. Of course, giving online services your cell phone number is just asking for trouble, especially, if you don't have unlimited texting. To get around this, setup a gmail account, and simply set it to forward all mail to your cell number. This method also works in reverse, provided your carrier offers an sms-to-email gateway. The number for T-mobile is 500, so you just send an sms in a special format to 500, and it will send an email to the email address. You can't use gmail as a buffer for that, but you can get an alias from your carrier.
