Trade devices? Pantech UML290 USB device for MiFi 4510...
I have a Pantech UML290 broadband USB device. The portable MiFi would better suit my needs. I am still under contract and don't want to pay full retail just to get the MiFi.
I also have the CradlePoint CTR router that works with the Pantech, so functionality is basically the same other than having a device that is batter operated as the MiFi.

I mainly use my current USB device to connect my WiFi only iPad. I have had no problems with the Pantech or CradlePoint router. Occasionally when first connecting I do have to switch the router off/on to get the iPad to connect, but otherwise works great. I want to be able to take my wifi with me is the reason for wanting to trade.
