  1. I updated ios 4.3.1 in my Iphone its really improve battery life cool one .!!!

    • Did you apply this update on Iphone 4? Does this improve the battery life of Iphone 4 also?

    • yes Yasir i updated iphone 4 its give good battery life and i thing charging its take longer then earleir .

    • yup..battery lives longer…can play Angry Birds for like whole day without charging..though i’m still quite expectant that on this update they will lift the “ban thing” on the activation of FaceTime..

  2. I am still using 4.2.1 on iPhone4
    Just waiting to make sure that jailbreak is avalable for 4.3.1 😉

  3. the new IOS is really much better, it makes more stability and keeps battery more healthy than the previous version, thanks apple for keeping us updated.

  4. Doesn’t help iPhone 3G? Also, my 3G lost the WiFi button after I upgraded the last time.

    Anyone know how to fix it?

    • disappearing wi-fi button, that’s wierd.. anyways, you can always restore it to it’s original settings once you’re connected the device to iTunes.. it’s always says there that “if you’re experiencing problem, click Restore”, this will returned back your device to its original factory settings, but take note, this procedure will delete all your data on your device, though at the end you have to restore from a backup or you can restart as a new device. Good luck!

  5. hi sir, just want to ask, i had my iphone 4 just today and its on ios 4.3.1 and i dont see the mms settings or apn settings. any idea on how to enable this settings on iphone 4 ios 4.3.1?

    • phil, to set your MMS setting regardless of the IOS firmware you’re using are as follows.
      (1) Tap Settings and tap Messages.
      (2) On Messages make sure that the MMS Messaging is ON, if OFF swipe it ON.
      (3) Back to Settings, tap General.
      (4) On General, tap Network – on Network you’ll see the Cellular Data Network, tap that.
      (5) There you’ll have the Cellular Data and the MMS settings. Change the APN as per the setting provided by your cellular-provider. The setting for this usually comes automatic with the SIM, if not contact your cellular-provider.

    • hi thanks for the reply, the only problem is in ios 4.3.1 there is no cellular data network. when i go to settings>general>network, the only settings there is enable 3g, cellular data on/off, data roaming on/off, personal hotspot, vpn and wifi. i think they remove the cellular data settings in ios 4.3.1.

    • I am facing the same problem with my Iphone, i just got it from STC before one week and once i update it the Cellular Data Network Tab disappeared.
      Please advise me
