There is a known issue where all J2ME downloads will fail on the T610 and Z600 devices using T-Mobile. Downloads to phones in which the OTA transfer is done via T-Mobile's network (ie. customers with T-Mobile service) - works fine on all J2ME devices with the exception of T610 and Z600.
Please verify which carrier he used and if he can reproduce the same using AT&T. This is a still a bug that appears to be network specific and not anything stemming from our end.
I'm not sure if it is related or not, but we are finding that these same phone models are having problems incorporating our network functionality (HTTP POST) that is working great on other models and carriers.
Is anyone having a similar experience? If someone has successuflly tested their networked funtionality on these devices with T-Mobile, could you please let me know if there was something special that was needed to accomplish this or could you share a sample of your working network code?
Thanks so much!
