So Here is how to register your phone as a developer phone FOR FREE....You can deploy upto 10 xap to your device, also u can unlock 3 Windows phone using 1 Live ID.(some people are saying they can deploy only 3 apps)
1.The main thing is to get a free student account i.e a edu email address.
So here goes,
You need to sign up,https://eims.maricopa.edu/MAW/MAW.html
At the signup page, you need to tick,
"I am a new student and have never attended any Maricopa Community College or Skill Centers." this option, then fill in the captcha and continue.
Next you need to give personal information, make sure you give your real information,
except thePost code SSN which probably everyone doesnt have, so u can generate a FAKE SSN,http://www.fakenamegenerator.com/social-security-number.php
here, and post code, you could just google up for a post code of "Arizona" or probably any postcode in the US would do.
After you finish signup, you will get an MEID, a email, and a password.
Make sure you save all these info with you, in a notepad or sumtin.
Ok now it takes sumtime to activate the account, as they say 20 mins, just give it 20 mins and then, go to https://eims.maricopa.edu/MAW/lookup.pl?req=passwd
, click NO, den put your details there, put the same password as before.
Now try to loggin to maricopa.edu/google/ or goto https://mail.google.com/
and use the Email and password.
Once you get access,
