Hi. Unless you will be allowed to retain your current plan, the new postpaid plans now are called myLifestylePlans. The base plan is 499 and your actual plan would depend on your additional packets. Similarly, the cashout for iPhone 6 would also depend on your chosen plan. Just call 02-7301300 for recontracting.
To have a faster discussion with recontracting hotline, you can choose your packets here ---- http://www.globe.com.ph/mylifestyleplan-info
