Blackberry Playbook(WiFi)+Blackberry Curve 9220

Hi,

I am from India currently using a Nokia E6 looking forward to buy a BB Curve 9220 & BB Playbook (WiFi) together. I know that the Display of Curve 9220 is very poor compared to Nokia E6 but as Blackberry will launch new BB OS 10 devices next year I don't want to invest in an expensive BB OS 7 phone. Next year I will buy a BB OS 10 based phone so you can say that Curve 9220 is a temporary device for me. Now I have never used a BB Phone or Tablet before so I have some queries & I hope that all members here will help me to clear my doubts.

Queries :
a) I know that it is compulsory to activate BIS in BB Phones to access BB App World, Stock Browser, BBM, FB & Twitter apps so is it same with Playbook?
b) I came across some tricks (APN Settings) which enables user to browse net via 3rd Party browsers like Bolt, Opera Mini. So after applying this trick I am gonna be able to use WiFi Tethering of Curve 9220 without activating BIS?
c) Again, do I need BIS inorder to use BB Bridge App?
d) Please suggest some best 3rd Party Apps (FB, Twitter, GTalk, Y Messenger, Email Client) for Curve 9220 that doesn't require BIS.
e) Is it possible to manually download apps from BB App World using BB Desktop Software & then transfer that file to Phone/Tablet for Installation?

P.S: I will be buying Factory Unlocked Curve 9220 to use with my !dea Gsm Sim & I hope you know that we don't have any Carrier Restrictions in India.

Thankyou :)

browser,fb app ,twitter, and app world can be accessed over wifi....but dere is no regular data plan for bb like android have
bridge doesn't require bis....it will connect via bluetooth or over same wifi network....
Im apps don't work on wifi.....like yahoo msn whatsapp...they reqire bis

Thanks stberry :)
Suppose I didn't activate any BIS plan but managed to use internet with that APN Settings tweak. Now if I sync PB with 9220 via Bridge App then in that case will I be able to use Internet in PB?

Please reply guys...

I haven't tried it without bridge without BIS. Why not activate BIS? Monthly payments are cheap.

Thanks Ishaq786 :)
Can someone suggest official Twitter, FB & Messenger app alernatives that work without BIS? Heard alot about SocialScope, UberSocial & eBuddy but am not sure.

Please reply friends :)
