Hi, I just signed up for the US T-Mo 200MB "unlimited" data plan about a week ago, with $5 off the regular price for 24 months on a loyalty promo, with 24 month contract also. As I was concerned that may not be enough data, I was told by the phone rep, that once I use my 200MB on 3G/4G, it will depend if there's a "slot" open for 3/4G, that's not being used by someone with a higher priced data plan. If a slot is open, I was told I'll still connect at the higher speeds, but as soon as that high speed slot is needed, I get throttled down to EDGE I assume. Anyone else hear of this, or is this pure bunk? I been using wifi and 2G mode to save my hi-speed for when I really need it. I'll try to use the rest of my 200MB up in a few days, which shouldn't be hard to do, as my month renews on the 20th. I'll try to see if this is true if I don't find out before. I did a mobile speedtest.net on 2G, first test was 101 down and 37 up, a second test showed 161 down and 76 up. A couple of tries said error connecting to speedtest.net Is that par for 2G? Any apps that may make 2G any faster? Thanks. PS I also got the Sensation 4G which I may swap for the G2x, per concerns in my other posts.
