Supported Frequency on T-mobile Samsung Galaxy Tab Plus 3G Version

T-mobile seems to be started selling the Galaxy tab Plus in 3G version. As far as i know that this mobile support 3G Frequency of 900/1900/2100 but when i see in the box it says 1900/1700/2100. I am really confused here and dont know which is correct. Does anyone get a confirmed Frequency range?

The original frequency of Samsung Galaxy Tab Plus is GSM 850 / 900 / 1800 / 1900 / HSDPA 900 / 1900 / 2100 MHz. So now it's at T-Mobile no longer available and you can "reserve" just yet. Keep your fingers crossed and hope that T-Mobile, the action somehow beckons.
