Compile errors in gsm-shield-arduino

I have found solution.
I am using arduino ide in 1.0.3 version (installed on my fedora by "yum install arduino"), but found that there is 1.5 version - but still beta.
In 1.5 there is one fix to F() function which I applied in my 1.0.3, which is one line in WString.h that needs to be changed:

#define F(string_literal) (reinterpret_cast<__FlashStringHelper *>(PSTR(string_literal)))

to

#define F(string_literal) (reinterpret_cast<const __FlashStringHelper *>(PSTR(string_literal)))
