Before you point to other thread lemme tell you what the difference is and what the uses are.
for us that like to keep newest releases around we have to contend with unhackable firmware and some sites not recognising model. such as opera mini and n85. and it may take months to resolve this.
so i have choice either get computer dloadable version without certificates (and consequently not being able to change permissions in app manager to always allow) or get it with phone browser (but because phone is not recognised you get crappy lo res icon). and because our firmware is unhackable we cant manualy change it.
well heres the version that solves this, signed and hi-res icon (still little blocky but really improved over the default)
