NO dates given, but: 1. Paperless billing. 2. mytmobile.com for prepaid users 3. Add a line on tmobile.com 4. tmobile.com redesign.
they made a few minor changes to tmobile.com a few months ago, the biggest update recently was to mytmobile.com.
I expected to see My T-Mobile for prepaid users. I read a press release online some months back that Ericsson would provide services to T-Mobile, an item related to prepaid service was mentioned in the release.
