If you really want an iPhone then upgrading from the LG Xpression is a good idea. I find the iPhone 6 to be overrated.
To upgrade your LG Xpression 2 should not cost anything it should go along with the app. This is on a iPhone 6 Plus.
It is really up to your personal preference if you want to wait for the iPhone 6 or upgrade now. There is a lot of speculation the the iPhone 6 will be a great phone.
Yes the iphone 4 is better so you should upgrade to the iphone 4.
Not unless you want to lose your unlock
Upgrading to the iPhone six would be so bad. The iPhone six is one of the newest phone on the market.
you should i have a iphone 3g and since the 4.0 update it looks better and it has so many new features you should its awesome
The cost will depend on who your mobile phone provider is so ask them. It should not be overly expensive as its not the latest model of the iPhone.
Definitely get an iPhone. You'll love it and there's so much you can do with it. In fact, I'm answering this question from my iPhone.
An ipad Air2 would have more functional capability than an iPhone 6 and might be a better choice for Christmas.
Plug your 'i' device into your computer/laptop and go onto itunes and it should say that there is an update.
It might be a bit of a wait s the iPhone 5 is not out yet, best wait for that version.
hell no unless you want an iphone that goes slower than a computer made a decade ago, crappy youtube, and overheat central.
