Ok Guys i finally Solved My Missed call problem!!!
I dont know if anyone has tried this but here is simple solution
"Thanks to Good Fellas over at Customize"
You can Modify the String Value right from the customize and hence fixing your "Call failed " Call Failure "
Issue
This is very simple.
Step: 1 - If you don't have Customize download it by Installer.App
Step : 2 - Go to Customize >>scroll to SpringBoard Strings
Step: 3 - Go all the way Down to Call Fail & Change it to "Missed Call"
Step: 4 - Fixito !!
Now test your phone - Call it let it goo all the way till you get to your voicemail
It should display {"Missed call" "Call Failed"}
like Before {"Call failed"
"Call Faliure"}
The only Exception is that - Whenever you get a call failur error like if you try to call & there is no signal you phone will display "Missed call"Call Failed" Which isn't a big problem because you can see that there is no signal so you know that there is a an error in signal or connection .
But atleast now You can see MISSED CALL..!
I hope This Helps
This method only changes the call faliure error .. this will not show that who called like "john Missed call"
Someone can maybe look into this little more to fix it so that it shows the caller id.. As i m allready working on this ... to get it corrected ... i think soon i will get this to work where it will even show you Who's the missed call is from
Thanks to Modmyiphone.com Thanks to Customize and thanks to all Hacker developers and everyone who is doining whatever They can !!
