刷IOS那是老黄历了。 现在新出的3560x的许可不是通过换IOS实现的，而是要买paper License。 就是说 现在3560x里的ios都是一样的 ，只不过靠不同的paper license来区分功能。 这其实和windows7很像，windows7的安装光盘都是一样的，装在硬盘上也一样，但是序列号不一样，所以分为家庭版、专业版、旗舰版。如果你想把家庭版换成旗舰版，你并不需要重新安装windows7，而是输入一个旗舰版的序列号就行了。 你需要购买对应的paper license来升级成ipbase。 下边是相关的列表价，仅供参考。 Catalyst 3560-X Series Product Activation Keys C3560X-LIC= Product Activation Keys for 3560-X Series C $0.00 C3560X-24-IOS-S-E C3560X-24 IP Base to IP Services factory IOS Upgrade C $6,000.00 C3560X-48-IOS-S-E C3560X-48 IP Base to IP Services factory IOS Upgrade C $6,000.00 C3560X-24-L-S C3560X-24 LAN Base to IP Base Paper License N/A $1,350.00 C3560X-48-L-S C3560X-48 LAN Base to IP Base Paper License N/A $2,100.00 C3560X-24-S-E C3560X-24 IP Base to IP Services Paper License N/A $6,000.00 C3560X-48-S-E C3560X-48 IP Base to IP Services Paper License N/A $6,000.00 C3560X-24-L-E C3560X-24 LAN Base to IP Services Paper License N/A $7,350.00 C3560X-48-L-E C3560X-48 LAN Base to IP Services Paper License N/A $8,100.00 L-C3560X-LIC= Electronic Product Activation Keys for 3560-X Series N/A $0.00 L-C3560X-24-L-S C3560X-24 LAN Base to IP Base E-License N/A $1,350.00 L-C3560X-48-L-S C3560X-48 LAN Base to IP Base E-License N/A $2,100.00 L-C3560X-24-S-E C3560X-24 IP Base to IP Services E-License N/A $6,000.00 L-C3560X-48-S-E C3560X-48 IP Base to IP Services E-License N/A $6,000.00 L-C3560X-24-L-E C3560X-24 LAN Base to IP Services E-License N/A $7,350.00 L-C3560X-48-L-E C3560X-48 LAN Base to IP Services E-License N/A $8,100.00
不要升级 卖给我吧
不能升七，你的6系统有没有越狱，如果越狱了可能是插件冲突，
升级到7不能回到旧版本，所以升7要慎重
可以的，可以直接用iTunes重新刷机。
作为一个4龄的苹果使用者建议千万别升系统，现在苹果为了让消费者更快的更换新手机赚钱，搞的原先手机升系统就卡，卡的不要不要的，现在也就7升系统没有危险！
