You won't be able to get your phone unlocked by posting your IMEI (unless someone who works at Motorola with access to their database is feeling generous). Best thing to do is either call T-Mobile and ask how much they charge to unlock it, or (if you have a usb cable) pay around 20-30 dollars for unlock software (e.g. http://www.phoneblitz.com). There might also be a free method to unlock the v188 - try a google search.
Nothing yet, But am still looking but if you ever to discover the unlocking codes pls notify me...it will be the same here. Thanks in advance
