United Explorer Business card with 50,000 miles sign-up bonus

This Flyertalk thread has dug up a way to make the 50,000 United MileagePlus offer for the Business card offer available to everyone.

I just applied using this method (Step 1-3 are taken from Flyertalk!).

1. Login to united.com and then see if the 50k offer appears

2. The offer never appeared for 50k, so instead I clicked on Apply Now for the 30k Business Explorer offer.

3. Once that application loaded and showed my pre-populated name, etc., I erase the URL, and replace it with this one

https://www.theexplorercard.com/UMPC…4M&REFERID=TEC

4. I went back to united.com and went all the way to the Club card offer. Suddenly the annual fee was waived and when I clicked back to the United Explorer business card he 50,000 offer appeared.

5. I took screen shots and applied right away.

The card is very much the same as the personal card (which has just gotten rid of the foreign exchange fees finally). This is a good opportunity if you be eleigible for a business card offer.
