How do you copy/paste in a smartphone?

There's also the Optimus F3Q, which should be compatible with Straight Talk if you unlock it.

EDIT: If you can find one...

There's also the Samsung Galaxy S Relay, which can be found on ebay

PushBullet has enabled universal clipboard -- meaning if you install the Desktop client and the Android app (I believe you need to give it additional access to something). You can copy and paste from PC/Android.

OR give AirDroid a try.
