IPhone 5, 4G(HSPA). Enable LTE option?

I own a xperia z before, and it has connected to 4G (HSPA). When i used my iPhone. It only displays 3G. But according to my research it will display to 4G when connected to HSPA. I see the "Enable LTE" option under Cellular Data and it is turned OFF. Should i turn it on to get the 4G(HSPA) signal?

LTE is only slightly faster than 4G, so it is basically the same thing. To connect to 4G, go to the Cellular Data tab you should see a "4G" slider. Turns this on. Your phone should connect to 4G within the next 2-3 minutes. This isn't instant because the cellular receiver first needs to clock itself up. If you do not connect to "4G", there probable isn't any in your area.

  • How to use an iPhone 4s key to enable siri on my iPhone 4? I can't find any updated guides on how to do this. I don't want to go a free route, since I have access to an iPhone 4s. The iPhone 4s is not jailbroken, but the iPhone 4 is. I've read through the process for getting the key, and I think I can do it. Also, I have a mac. My question is, how do I actually go about setting everything up? I have Acid Siri installed currently, is it an acceptable GUI?
