Need to clear my knowledge regarding OTA

If I choose to get hold of a MIDlet using the GPRS technology, what dose it looks like in my cellphone. Do every cellphone have their own �GPRSbrowser� or is the only way to download it by the �WAPbrowser�.
I have a very unclear picture about OTA (Over The Air) technology. Best of all would be to get hold of an article using the OSI-model to describe a complete overview of a client getting a list of available MIDlets suit for downloading, choosing one, downloading it. But at this point I�m glad if someone could hook me up with something to do with OTA at all.

Hi,
Have a look at the Nokia MIDP Application Developer's Guie for Nokia Devices Version 1.0. You can find this pdf files in the Nokia Forum site. Section 11.2 of this guide gives a introduction to OTA. It alks in detail about the complete MIDlet lifecycle, the JAD descriptor etc. and the steps involved from finding the MIDlet list in web to actually donwloading one, using and then removing it.
I hope it would be a good beginner's guide.

After reading just a few pages in the Nokia MIDP Application Developer's Guide for Nokia Devices Version 1.0 it suddenly becomes much more clearer. I have on question though. They say thar users with PcSuite can download MIDlets from there. Whats its that when you use your Computer as an link between your cellphone and internet? Otherwise Nokias says there only one other option to download (OTA) and thats WAP (the most common)?

Hi,
I am not sure if I got your question right ? Nevertheless I will try to answer your question.
Using Nokia PC Suite and Nokia DKU-5 cable you can transfer MIDlets directly to your mobile. During uploading the MIDlet you specify the .jad file name to upload. This file contains the information about the JAR file and its size, which is then uploaded into the mobile device.
For learning more about OTA, you can download a freely available tool called Deck IT from PyWeb. It provides a WAP Emulator, which you can use to download MIDlet's from the wap sites and test them.
Let me know if I understood the question.
Regards
Ritesh

Well kind of, What I really wanted to know was diffrent techniques to get the MIDlet from det server to my the phone Over The Air. But I got that sorted out in this topic. About Deck IT is it really possible to have the emulator download jad & jar? I mean when I installed Deck IT I got a old Nokia, I doubt that it has support for J2ME?
