Sprint J2ME differences

We are having trouble getting our J2me GSM games working fully on Sprint devices. We are using MIDP 1.0. Application currently works but we think tilemap drawing has problems.

Is there any information out here/there on the differences between Sprint's j2me flavour & others?

Also, is there a downloadable working example of a Sprint game like app? We'd like to compare what we are doing to a working game like example to solve these problems.

Last - this website is nice but is there an official Sprint Developer Support? We've been using net based uploaders to test the games but I hear this charges the phone per kilobyte! Is there a more official way to develop for Sprint phones?

Thanks.

Sprint

You probably want to visit http://developer.sprintpcs.com

You will find information about the Sprint specific API extensions to MIDP. There is a developer forum, though it's pretty bad.

What phone(s) are you testing? Sprint extended the APIs but did not change the MIDP spec. What you are probably experiencing is the horribly broken JVM implementations that are out there. On many phones you will find some APIs just plain don't work or even cause the phone to reset.

As far as a sample game, I don't happen to have anything laying around though I've seen arcade style examples that run fine on some Sprint phones.

The only "offical" way to install J2ME applications is over the air on the Sprint network so there is no avoiding the per kilobyte charges. I recommend an "unlimited" vision account. On some phones you can install applications through a cable using software like BitPim (see downloads section). The Treo handsets also allow you to install applications through Hotsync.
