Bigger phone or sms memory?

[SmOg]

Is there any way to make phone memory or sms capacity bigger? Example: remove some "useless" function to make place for phone memory? In N6150 v 5.23 there is 150 phone memory, but when i upgrade it to v p5.23 i will be only 100 (other plus functions "steal" places) Any idea? :rolleyes:

Sorry for my english :p
