i wireless Transitions to HTC S621

i wireless has started selling the S621 variant of the HTC "Excalibur." The only two differences that I have noticed between the S620 and S621 so far are:

• The S621 has symbols (in blue on the keys) more commonly used in the U.S. vs. the more European-centric symbols on the S620. The “J” and “L” keys have the symbols for the pound and euro on the S620. These are replaced with the “@” and “=” on the S621.
• The S621 has predictive text. The S620 does not.

Don't know which one you have? Look underneath the battery, in the lower, left-hand corner of the IMEI label. The S620 says “EXCA200.” The S621 says “EXCA100.”
