Running J2ME on my OWN HP ?

Hi all, especially to our special guest Jonathan Knudsen,

Though I am not new to J2SE and J2EE (I am a SCJP), I am very very very new to J2ME.
I know J2ME is a very exciting place... just as exciting as J2SE and J2EE.
Apart from knowing that J2ME is a much shrink down version of J2SE, I don't know anything more about it. So please excuse me if my questions are rather elementary.
Questions :
1) I know that we have emulators (if that is what it's called) for developers of J2ME to test their masterpieces (programs). If I buy a Java enabled phone, can I run my OWN J2ME program on it ? Then it would be cool to have my own program running on my own phone (nobody else has this prog in their HPhone).
2) Will I cause my phone to crash if my prog is not written properly ?
3) Will I void the warranty of the phone by running on own J2ME prog on it ?

Thanks !

Answers:
1. Yes, you can run your own MIDlets on your own Java-enabled phone. I have a Motorola i85s and a Nokia 3650, both of which I use for testing. The procedure for deploying depends on the phone. For the i85s I have a serial cable. For the Nokia 3650 I use IR to transfer the MIDlet suite.
2. No, that's one of the best parts about using a VM on the phone: about the worst thing a MIDlet can do is bring down the VM, not the phone.
3. No, you will not void your warranty by running your own program.
