First off, sorry for the delay in replying & thanks to all the members for their help, especially toxic & hotshot.
1. I understand that since the 5130 XM has a 3.5mm jack, it can be used with any standard headphone. However, is it also possible to hook it up to external speakers via an amplifier through the line/phone in? If yes, what will the audio quality be like? Will it depend on the audio capabilities of the phone or the amplifier?
2. Is the music player interface & overall ease of use comparable to a SE walkman phone? [meaning- does transferring files from the PC to the phone automatically organize them into albums,artists etc.?] [Sorry if it seems like a stupid query given that it's a music phone, but I've had a Nokia for a while now.]
3. What lossless formats [eg. FLAC], if any, does it support, either out of the box or with some tweaking/modification?
4. I've heard about slow-down/lag in phones when fitted with a memory card, generally speaking. Does the 5130 XM suffer from the same? In other words, can I safely load it up with an 8GB memory stick?
5. What is the extent to which the memory can be expanded? I've heard about it even supporting a 16GB card [some review somewhere].
6. Is there any possibility of increasing the display brightness via some tweak/application?
That's it [for now]. Don't hesitate to shoot me down if I've gone out of line & I should've created a separate thread for this.
Thanks!
