Wow, that was FAST!

I was using another CDA (HK) and SEUS updated mine to R3EA037. Maybe that generic America CDA didn't need an update?! One thing you can check, try streaming youtube. If you can do it, that means you have the fix already in R3DA028 and perhaps there's no furthur updates needed for that CDA.

The fix came with the update looks something like
...
<firewall-traversal-interval>15000</firewall-traversal-interval>
...
in tpa\preset\default\default.xml (not where you put custom_update.xml)

By the way, you might want to mask out your IMEI number, in case there are some bad apples out there! :D
