Does the BlackBerry Curve 8900 for T-Mobile have text message signature? - Justice

No, there is not a signature for your text message. There is the option to do it for your emails, but not text messages.

I’m looking at the T-Mobile Dash 3G, can you tell me what 3G Data Technology is, what Wi-Fi calling is, what Sync means and it means when a cell phone has Windows Mobile 6.1 OS? – Melissa

3G data technology means you can access the Internet on your cell phone at faster speeds than the normal EDGE network. Wi-Fi calling is very similar to a Voice over IP calling system such as SKYPE. However, for some cell phones that have the ability to do Wi-Fi calling on T-Mobile, you are able to use a T-Mobile Hotspot to make calls using Wi-Fi as opposed to your normal minutes. Lastly, Windows Mobile 6.1 is just the operating system for the phone. Similar to a PC’s operating system, it is a smaller scale operating system set to work on your mobile device.
