Hello friends

I bought a Samsung Hero GT-3213K yesterday.
when I bought it yesterday, I thought it was a great phone with 3g and HSDPA at such a low price.
Everything has worked great since then other than the fact that I am not able to install any jar file
both offline and online, I always get the same error message that "Download Failed Downloaded JAR are invalid"
any application that I tried to install got the same result.

When I contacted customer care about this I only got the response that third java games is not supported on my phone
and that I will have to get the applications from GPRS only. (I don't know what they meant)

As of before I had tried to install the same kind of applications in Samsung Hero GT-3210 which has all the same features other
than the fact that that it does not have a front camera for video calls.

Anyone out there PLZ help me!!!!

most samsung mobile doesn't support jar files. a known fact. you'll need jad fine. some support jar files of upto ~300kb. not higher than that.

That's because those are incompatible with newer phone's OS.
