Would updating iphone 3g to 4.2.1 allow video recording and mms messaging?

I'm getting an iphone 3g that is updated to 4.2.1, will i be able to send picture messages and will the phone have the APPLE CAMERA APP? Thanks

Added (1). Btw the iphone 3g hardware is capable of video recording

No, hardware changes are not possible through software updates. Sorry.

You may consider upgrading your device.

  • Will updating my iPhone apps affect my phone speed as how updating the Operating System (OS) will? Currently I'm using the iPhone 5s on iOS 8.3 I know if I were to update my phone to the latest OS I may notice some slowdown on my phone's performance, since it may not have the "muscle" to handle certain functions. Many apps now are optimised for iOS 9 and/or the 6th generation phones. Will my 5s' speed performance slow down if I update my apps? Will the app's performance slow down?
  • Video recording apps for the iPhone 4s? Me and my sister are filming a funny video which requires pausing during a recording. I was wondering if anybody knows any video taking apps for the iPhone 4s that allow you to pause during the recording of a video.
  • STRAIGHT TALK, iPhone 4 picture and video messaging not working? I just switched from AT&T to Straight Talk for the everything unlimited plan. However, I can't send picture or video message and the internet is really slow. I called Apple and they tried everything to help, but nothing work. They suggested I should Google for help. Can someone please help me? Thanks. I called Straight Talk they couldn't help either. My phone is already unlock by At&t.
  • Safari won't allow me to play youtube video in background or when phone is locked? I used to be able to. When I try playing the video after going to home screen (I have an iphone) and press play, it just plays music from apple music. Is there any way I can play youtube videos in background or when phone js locked? I would appreciate it. I can't find anything online where someone has the same problem:/
