Will my iphone be able to get ios 7?

My iphone is unlocked and flashed to a company named page plus. When ios 7 comes out, will my phone get it?

Depends of the model of your iphone: 5 will get most of the upgrades, 4/4s some and 3/3s none.
Then, the IOS7 will erase your jailbrake.

Iphone 4.4s.5 can get ios7. Your flashed so you might lose the flash

It doesn't matter which carrier the phone is with or the configuration. It matters which model it is.

The 4, 4S, 5, 5S & 5C are getting it.
