Questions about T-Mobile SDA

[Guest Zerynov]

Hi all! I need some information about my T-Mobile SDA.

(sorry for my bad English)

1. How can I find out if have IMEI lock?

2. Is there a support for this device (Internet site)? (for example ROM update etc.)

3. After Hard reset default language is German. I'd like to have an English language as a default one. How can make it? (may be ROM update?)
