iPhone 4 new SMS writing

[naloul]

Hey all,

i have an iPhone 4 on ios 4.3.5 (non-jailbroken). i have been seeing an issue: when i want to write a new SMS, and i chose to enter a mobile number to send to i used to get the big digits keypad to insert the number, lately i don't get that big digits keypad, instead i get the normal keypad with the letters and everything...any idea??

Is it the default SMS app doing that? Have you tried a hard reset?
