Looking at the official "supported" iOS versions, I believe 5.x and 6.x are supported. I know it is a long shot, but is there any way to get iOS 4.x support?
I can't say for certain, but I would guess that it is not likely, or they would probably have done it in the initial release. Now they are moving on and focusing on Android, so iOS is not the focus right now, at least as far as supporting older versions is concerned.

I'm interested in developing a Telegram app for the Blackberry os 7. Yeah, the old one.
So, can I still develop, deploy and why not, release on BB OS7, or it's not possible any more.
Don't think this is really a Stack Overflow question, but yes. You can still dev for it. You'll just struggle a bit to find support for it, and libraries will not have been updated in a long time.
As you can probably guess, my knowledge of coding is very limited. Nonetheless, I do know a little Java. I have Eclipse and was wondering if I could use it to code for iOS iPhone/iPad applications. I know that I would almost certainly have to use a language other than Java, but I'm clueless as to what packages or plugins I would need to install in Eclipse to use it to code for iOS. If you guys could answer this question in extreme detail or link me to a very good sequence of video tutorials, I would be extremely grateful.
Yes you can!
If you can live with coding ActionScript, which should be easy to learn with a Java background, you can use Eclipse & AIR to code for iOS (and Android at the same time)

Be aware that many apps in the store have been build on this platform, and the community is pretty alive and supportive.
The short answer is, "not natively."
Apple pretty much restricts "native" iOS development to XCode which, as #Bob said in his answer, is only available for OS X. So that means no Eclipse or Java-based development. However, there are several cross-platform development frameworks and tools that work to varying degrees of quality. Here are a few, in no particular order:
PhoneGap
Appcelerator
Corona
Adobe AIR (see answer by #dogsgod)
There are others, but those are ones that I've at least heard of and might have tried a little bit. Some, like Appcelerator, have IDEs built on Eclipse, so at least the dev environment would be familiar.
IOS apps are written in Objective-C or Swift using XCode. (This also means you'll need a Mac to do so. XCode is only available for OSX.)
So unfortunately this means the answer to your question is no. You cannot use Eclipse to write an iOS app.
I have an App. that was built for BB OS 6. Wanted to know if it will work on the new OS 7 without any glitches.
If not, can it be ported without re-doing the entire thing.
It will work but as the devices probably will have different resolutions maybe you will have to made some code changes so de fields adapt better to the screen even if the code behave dinamically.
You can see it if you try your app in the simulator.
It will work without making any changes, as Blackberry 7 has backward compatibility for the builds. You might get some regulations issues, if your program is coded to behave dynamically then no issues.
Also, You don't really need to build again. Just go ahead and install on Blackberry 7. It will work.
I am trying to target a Blackberry application to multiple devices, since there are advanced graphics needed. I would like to avoid writing multiple versions (as suggested here). The target is OS version 5.0, and so far it works as expected on storm2 simulator.
The issue is when I run it on the Bold simulator, the EditFields are not accepting input from the keyboard.
I can't seem to find any example how actually go about supporting multiple devices.
Thanks,

There are a lot of good links in this question.
In particular, Marc's answer contains links to actual projects which support many OS versions that you can explore and mimic.
Use only the components available to 4.5 and it should work on all different OS versions.
Or make your own custom components.
What is difference between Blackberry OS 4.6 and 5.0?
Thanks.
Two major differences that I've found are that SQLite does not work on anything below OS5.0 (though it only 75% works on OS5.0 anyway) and that BrowserField2 does not work in anything below OS5.
Really? Try to compile your code using a different JDK and see what happens :)
That's sort of a vague question. From the developers side you can look at the differences between the 4.6 API and the 5.0 API yourself. The major additions I noticed were the accelerometer classes and the ConnectionFactory.
From the user side you can google any number of articles on new features for 5.0. Here are a couple I found: BoyGeniusReports, PCMag.
If you tell us more about your application we might be able to tell you whether you'd likely need to use the 5.0 OS or not.
