My work uses BES. I found out that our internet connection blocks magmic.com - So I can't connect through BES.

I have tried to configured TCP settings in the blackberry for T-Mobile using APN: wap.voicestream.com (with and without APN username & APN password)

This problem happens with both games I have (Medieval Kings Chess II & Texas Hold'em King 2). In THK2 (configured auto and manually for T-Mobile(US)) I get the following error:
Network Unavailable Error_Code: 502

Any help would be much appreciated. I look forward to buying more games once I get these to work.

Thanks,

Ken
