Positive and what I did not know until now (my cell phone: Samsung C3050 "phone without manual"): Mobile phone with the cable connected to the PC charges the battery. who will however call in this approx 90min or wants to call, must cancel due to the cable shortly charging (cable from the PC), crawl under the table or clean-call into the phone.
Negative: I advise everyone from about wanting to use the "Fill" cable a memory card. the data transfer rate is in VBG. with my C3050 for about 300kB / sec. !!!
TIP: better the memory card from the phone company (previously MP3 player or similar end!) And an SD card reader or USB adapter directly into the PC. so are with me about 3.3MB / sec. it (no-name micro-SDHC card).
SUPPLEMENTARY this: With the newer SDHC cards (Class 10) passable 16MB / s are now in it.
