SQL grouping

David, let me know if this should not post here.
 
I have a file that contains data looks something like this:
 
Phone#         Phone Ext#    Feature
1234567980      1234567       ABC   
1234567980      1234567       DEF   
1234567980      1234567       XXX   
1234569999      9994567       GXX   
1234569999      9994565       XXA   
6019991234                    ABC
 
 
Is there a easy way to transform it to look like this using interavice SQL if I 
know that the most feauture an unquie phone+ext can have is 8?
 
Phone#      PhoneExt#     Feat1    Feat2    Feat3    Feat4    Feat5    Feat6    
Feat7    Feat8            
1234567980   1234567       ABC      DEF      XXX
1234569999   9994567       GXX      XXA 
6019991234                 ABC
