Hello Wonder users
I remember when I first became flashaholic was when I using my i8150.
Anyways my personal opinion is GB rom was the best overall for speed and reliability. My favorite was Black Notes v2.
I know you cant have for instance, BBM..so another alternative I found to be best was CM9 based (4.0.4). You can use BBM and other most apps upto date, although battery consumption is slightly higher but not as much as CM11.
Guys just a reminder..be sure to purchase a new battery as it is high time to replace it..in order to experience the best out of your favorite ROM.
All the best for xda and galaxy wonder users in particular.
I'm only helping the community coz the community is helping me.
