@fullblast: thx for replying, so you do have Multitasking enabled, right? I don't care much about the winterboard, i like the original look.
@Frenzy_2020: i know that some users are facing problems with OS4, and some don't. I appreciate your feedback, as you tried it without multitask and your phone was slow. Thanks for your reply.
As i have a spare phone 3G, I will try on it and will post the results soon.
Thank you all for your feedback.
